The object is accomplished with an optical element including a light guide plate; a switching λ/2 plate capable of switching a phase difference between zero and λ/2; and a first optically anisotropic layer that is arranged between the light guide plate and the switching λ/2 plate, is formed using a composition including a liquid crystal compound, and has a liquid crystal alignment pattern in which an orientation of an optical axis derived from the liquid crystal compound changes while continuously rotating along at least one in-plane direction of the first optically anisotropic layer."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Optical element and image display device","description":"An object of the present invention is to provide an optical element capable of widening a field of view of an AR glass or the like; and an image display device using the optical element.
